Description

Technical Field

[0001] The utility model relates to the technical field of tower equipment processing, in particular to a release groove processing machine. Background Art

[0002] When tower equipment repeatedly undergoes the operation process from low temperature to high temperature and from high temperature to low temperature, with the increase or decrease of the operating temperature, the equipment shell will expand or contract. The skirt support connected to the tower shell will inevitably be affected by this phenomenon, resulting in additional stress at the top of the skirt cylinder. This additional stress may cause damage such as weld cracking. To relieve this stress, in conventional designs, generally, methods such as increasing the wall thickness of the equipment shell or the skirt cylinder, specially treating the connection weld between the skirt and the tower body, or installing a stress release groove on the skirt are considered to relieve stress fatigue damage.

[0003] When processing the release groove, a tooling is used to fix the groove base, and then the tooling personnel fix other plate parts on the groove base for splicing. Common tooling fixtures generally include a processing table, on which a clamping member and a positioning device are provided. To improve the flexibility of the release groove during processing, in some processing tables, the clamping member is installed on a movable plate, and the movable plate can adjust the angle of the clamping member by rotation, thereby increasing the flexibility during the processing of the release groove. The movable plate is rotatably connected to the processing table, and the groove base exerts a relatively large pressure on the movable plate, and the pressure mainly acts on the connection between the movable plate and the groove base. Therefore, during long-term use, the movable plate will be unstable during the process of supporting the release groove, affecting the operation safety. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a release groove processing machine to solve the problem that during long-term use of the existing release groove processing machine, the movable plate is unstable during the process of supporting the release groove, affecting the processing safety of the release groove.

[0005] To achieve the purpose of the utility model, the utility model is realized through the following technical solutions: A release groove processing machine includes a base, and two side plates are provided at the upper end of the base, and the side plates are fixedly connected to the base.

The fixed seats are fixedly connected to the side of the side plate away from the positioning frame. A groove allowing the positioning disk to penetrate therein is opened at one end of the fixed seat facing the positioning disk. A positioning bolt is assembled on the outside of the fixed seat. The positioning bolt passes through the fixed seat and is threadedly connected to the positioning hole opened on the outside of the positioning disk. Each positioning hole is evenly arranged in the circumferential direction of the axis of the rotating shaft.

[0011] A further improvement lies in that the rotation adjusting member includes a rod bracket. The rod bracket is fixedly connected to the side of the other side plate away from the positioning frame. A worm and a worm gear are arranged inside the rod bracket.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0023] According to Figure 1 , 2 , as shown in FIGS. 2 and 3, a release groove processing machine is proposed in this embodiment, which includes a base 1. Two side plates 2 are provided at the upper end of the base 1, and the side plates 2 are fixedly connected to the base 1. It further includes:

[0024] A positioning frame 4 is placed between the two side plates 2. Each side of the positioning frame 4 is provided with a rotating shaft 3, and the rotating shaft 3 is rotatably connected to the side plate 2. A clamping tooling is provided inside the positioning frame 4. The release groove seat body to be welded is fixed inside the positioning frame 4 through the clamping tooling.

[0025] A rotation adjusting member is installed on one side of the side plate 2 away from the positioning frame 4, and is used to control the rotation of the rotating shaft 3 and adjust the angle of the positioning frame 4. By controlling the rotation of the rotating shaft 3 through the rotation adjusting member, the facing direction of the positioning frame 4 and the release groove seat body can also be adjusted, so as to meet the processing needs of different angles.

[0026] A positioning disk 12 is rotatably connected to the other side of the side plate 2 away from the positioning frame 4. The positioning disk 12 is fixedly connected to the rotating shaft 3. A locking device for restricting the rotation of the positioning disk 12 is provided on the side plate 2. After the positioning frame 4 finishes rotating, the positioning disk 12 will also rotate accordingly. By restricting the rotation of the positioning disk 12 through the locking device, the accidental rotation of the positioning frame 4 during the processing can be avoided, and the processing safety of the release groove can be improved.

[0027] It is further noted that one end of the rotating shaft 3 is fixedly connected to the positioning frame 4. The end of the rotating shaft 3 away from the positioning frame 4 penetrates through the side plate 2, and the rotating shaft 3 is rotatably connected to the side plate 2. The positioning frame 4 is installed between the two side plates 2 through the rotating shaft 3. The rotating shaft 3 supports the positioning frame 4 to rotate around the axis of the rotating shaft 3 for angular adjustment.

[0028] For the specific structure of the locking device, please refer to the following description.

[0029] The locking device includes two fixed seats 14 provided above and below the positioning disk 12. The fixed seats 14 are fixedly connected to the side of the side plate 2 away from the positioning frame 4. A groove 15 allowing the positioning disk 12 to penetrate therein is provided at one end of the fixed seat 14 facing the positioning disk 12. A positioning bolt 16 is assembled on the outside of the fixed seat 14. The positioning bolt 16 passes through the fixed seat 14 and is threadedly connected to a positioning hole 13 provided on the outside of the positioning disk 12. Each positioning hole 13 is evenly arranged in the circumferential direction of the axis of the rotating shaft 3.

[0030] When restricting the rotation of the positioning frame 4, rotate the positioning bolt 16 on the fixed seat 14 and select the positioning bolt 16 into the corresponding positioning hole 13 on the outside of the positioning disk 12. Since the positioning disk 12 is fixed by the positioning bolt 16 and the positioning disk 12 is fixedly connected to the positioning frame 4 through the rotating shaft 3, the position of the positioning frame 4 will also be locked.

[0031] Regarding the rotation adjustment member:

[0032] In the preferred solution, the rotation adjustment member includes a rod support 6. The rod support 6 is fixedly connected to the side of the other side plate 2 away from the positioning frame 4. A worm 7 and a worm gear 5 are provided inside the rod support 6. The worm 7 is rotatably connected to the rod support 6. The worm gear 5 is placed below the worm 7 and meshes with the worm 7. A motor 8 is provided outside the rod support 6. The output end of the motor 8 is fixedly connected to the worm 7. The worm gear 5 is fixedly connected to the rotating shaft 3. The motor 8 drives the worm 7 to rotate. During the rotation of the worm 7, it meshes with the worm gear 5 to drive the worm gear 5 to rotate. Since the worm gear 5 is fixedly connected to the rotating shaft 3 and the rotating shaft 3 is fixedly connected to the positioning frame 4, the positioning frame 4 will also rotate accordingly.

[0033] This rotation adjustment member uses worm drive to control the rotation of the positioning frame 4. Worm drive has self-locking property. After the worm 7 stops rotating under the meshing of the threads between the worm gear 5 and the worm 7, the worm gear 5 and the rotating shaft 3 will not rotate back, further improving the stability of the positioning frame 4 during processing. Of course, other rotation mechanisms can also be used as alternatives, which will not be elaborated here.

[0034] Regarding the clamping tooling:

[0035] The clamping tooling includes two clamping blocks 9 arranged inside the rotating shaft 3. The clamping blocks 9 are slidably connected to the inner side wall of the positioning frame 4. On one side of the two clamping blocks 9 away from each other, there is an adjusting bolt 10. The adjusting bolt 10 is rotatably connected to the clamping block 9. The other end of the adjusting bolt 10 passes through the positioning frame 4 and is threadedly connected to the positioning frame 4. By rotating the adjusting bolt 10 and screwing the adjusting bolt 10 into the positioning frame 4, the adjusting bolt 10 will push the clamping block 9, and the two clamping blocks 9 will move closer to each other to fix the groove base placed in the positioning frame 4.

[0036] In the preferred solution, a limiting groove 11 is opened on the inner side of the positioning frame 4. A slider is arranged in the limiting groove 11, and the slider is fixedly connected to the limiting groove 11. The limiting groove 11 is fixedly connected to both ends of the clamping block 9. When the clamping block 9 slides inside the positioning frame 4, the sliders fixed at both ends of the clamping block 9 will also slide along the limiting groove 11 opened on the inner side wall of the positioning frame 4. By cooperating with the sliders, the limiting groove 11 guides the clamping block 9 from both ends of the clamping block 9, so that the clamping block 9 maintains a stable state during movement.

[0037] The base 1 has multiple two H-shaped frame bodies, and a support rib is arranged between the two H-shaped frame bodies. Both ends of the support rib are fixedly welded to the two H-shaped frame bodies. While ensuring that the base 1 has good strength, the base 1 is not too heavy, which is convenient for the staff to carry and transfer the entire processing machine.

[0038] The working principle of this application:

[0039] The release groove base body to be welded is fixed inside the positioning frame 4 through the clamping tooling. The motor 8 drives the worm 7 to rotate. During the rotation of the worm 7, it meshes with the worm gear 5, driving the worm gear 5 to rotate. Since the worm gear 5 is fixed to the rotating shaft 3, and the rotating shaft 3 is fixed to the positioning frame 4, therefore, the positioning frame 4 will also rotate accordingly to adjust the facing direction of the positioning frame 4 and the release groove base body, so as to meet the processing requirements of the release groove at different angles. After the positioning frame 4 completes the rotation, the positioning disk 12 will also rotate accordingly. By restricting the rotation of the positioning disk 12 through the locking device, it is possible to prevent the positioning frame 4 from accidentally rotating during the processing, improving the processing safety of the release groove.
